TECHNICAL FIELD

The present disclosure relates to a display control apparatus andmethod. More particularly, but not exclusively, the present disclosurerelates to a display control apparatus for dynamically controlling thedisplay of information in a vehicle; to a vehicle incorporating adisplay control apparatus; and to a method of dynamically controllingthe display of information in a vehicle.

BACKGROUND

It is known in automotive applications to provide a fixed display ofinformation for the driver. The information can for example, be outputto the driver in via one or more displays in the occupant compartment ofa vehicle. The displays used in vehicles include HLDF, head-up displays(HUD), and instrument cluster displays. A shortcoming of knowntechniques is that the driver has to look at a particular screen whichmay mean that they look away from the road. Certain tasks, such astuning the radio or selecting a navigation route, require attention fromthe driver and in certain instances this may prove distracting. Thisproblem can be compounded if the information is displayed on a screenpositioned away from the windshield, for example in a centre console.

It is against this background that the present invention has beenconceived. At least in certain embodiments, the present invention seeksto overcome or ameliorate certain problems associated with the prior artsystems.

SUMMARY OF THE INVENTION

Aspects and embodiments of the present invention relate to a displaycontrol apparatus for dynamically controlling the display of informationin a vehicle; to a vehicle incorporating a display control apparatus;and to a method of dynamically controlling the display of information ina vehicle.

According to a further aspect of the present invention there is provideda display control apparatus for dynamically controlling the display ofinformation in a vehicle. The display control apparatus may comprise acontroller having at least one electronic processor. The at least oneelectronic processor may be configured to control first and seconddisplays. In dependence on a determined gaze direction of the vehicledriver, the at least one electronic processor may be configured tocontrol a switching module to cause a first information data setdisplayed on said first display to be displayed on said second display.

At least in certain embodiments, the display control apparatus isresponsive to driver behaviour and controls the display of informationbased on the determined gaze direction of the driver. The displaycontrol apparatus can provide a multi-modal system integrating gazedetection and display interface controls. The display control apparatusmay be operative to manage the display of information within the vehiclein dependence on the gaze direction of the vehicle driver. A traditionaldisplay manager displays information in a fixed location (or locations)within the vehicle. However, the display control apparatus in accordancewith the present invention allows a dynamic display of informationwithin the vehicle, for example based on the priority of information,driver preferences (for example based on historic driver inputs), anddriver workload etc. The display control apparatus can thereby tailorthe display of information to a particular situation.

By providing dynamic control of the display of information, the displaycontrol apparatus can correlate the location where information isdisplayed to reflect driver behaviour. For example, if the firstinformation data set is displayed on the first display and the displaycontrol apparatus determines that the driver is not looking at the firstdisplay, the switching module can be operated to display the firstinformation data set on the second display. The transfer of the firstinformation data set can be performed seamlessly to move or duplicatethe first information data set on the second display.

The at least one electronic processor can be configured to control theswitching module to display the first information data set on saidsecond display in dependence on identifying that the determined gazedirection is directed at the first display. The switching module can becontrolled to display the first information data set on said seconddisplay when the determined gaze direction is directed at the firstdisplay for a predetermined period of time; and/or when the determinedgaze direction is directed at the first display repeatedly within apredetermined period of time.

The at least one electronic processor can be configured to control theswitching module in dependence on one of: priority of information;driver preferences; a determined driver workload; and a criticalitylevel defined for said first information data set. If the driverworkload is determined to be high, the display control apparatus can beconfigured to inhibit operation of the switching module; and/or toreturn the first information data set to said first display.

The at least one electronic processor can be configured to transfer thefirst information data set displayed on said first display from saidfirst display to said second display. A notification, such as a message,graphical symbol or an icon, could optionally be displayed on the firstdisplay to indicate that the first information data set has beentransferred to the second display. Alternatively, the at least oneelectronic processor can be configured to duplicate the firstinformation data set displayed on said first display on said seconddisplay. A notification, such as a message, graphical symbol or an icon,could optionally be displayed on the first display to advise that thefirst information data set has been duplicated on the second display.

The at least one electronic processor can be configured to control theswitching module to remove the first information data set from saidsecond display after determining that the determined gaze direction hasbeen directed at the second display whilst said first information dataset was displayed on the second display. Thus, the display controlapparatus can check that the driver has viewed the first informationdata set. A further check could be performed to require that the driverlooks at the second display for at least a predetermined time periodsufficient to comprehend the first information data set.

Alternatively, or in addition, the at least one electronic processor canbe configured to control the switching module to remove the firstinformation data set from said second display when the determined gazedirection moves away from the second display. The first information dataset could be removed at the same time as, or after the determined gazedirection moves away from the second display. The at least oneelectronic processor can be configured to control the switching moduleto remove the first information data set from said second display whenthe determined gaze direction is in a predefined direction, for examplean eyes-forward direction.

The at least one electronic processor can be configured to select saidsecond display from a plurality of displays in dependence on adetermined gaze direction of the driver. If the vehicle comprises athird display, the display control apparatus can select either thesecond or third display for display of the first information data set.The display control apparatus can, for example, select one of thedisplays in dependence on a determined gaze direction of the driver, forexample to display the first information data set on a display mostclosely aligned with the current gaze direction of the driver. The thirddisplay could, for example, be in the form of a head-up display (HUD) ora dashboard-mounted display.

The at least one electronic processor can be configured to receivesensor data from at least one eye tracking sensor; and to determine thegaze direction of vehicle driver in dependence on the received sensordata. Alternatively, the at least one electronic processor can beconfigured to receive the gaze direction information from an eyetracking apparatus.

The display control apparatus can be configured to record historicaldata to determine driver behaviour and/or preferences. Based onhistorical driver behaviour, the display control apparatus can determineif the driver prefers visual or audio output of information. If thedriver prefers audio behaviour and the determined gaze direction is notcoincident with the first display, the display control apparatus can beconfigured to output the first information data set in an audio formrather than audio-visual or visual information.

According to a still further aspect of the present invention there isprovided an eye tracking apparatus comprising a display controlapparatus as described herein.

According to a yet further aspect of the present invention there isprovided a vehicle comprising a display control apparatus as describedherein. The vehicle can comprise first and second displays. The firstand second displays can be spatially separated from each other withinthe vehicle. The first display can be a console-mounted display, such asa HLDF). The second display can be an instrument cluster display or ahead up display (HUD).

According to a further aspect of the present invention there is provideda method of dynamically controlling the display of information in avehicle. The method may comprise displaying a first information data seton a first display and displaying said first information data set on asecond display in dependence on a determined gaze direction of thevehicle driver.

The method can comprise displaying the first information data set onsaid second display when the determined gaze direction is directed atthe first display.

The first information data set can be displayed on said second displaywhen the determined gaze direction is directed at the first display fora predetermined period of time; and/or when the determined gazedirection is directed at the first display repeatedly within apredetermined period of time.

The display of said first information data set on said second displaycan be controlled in dependence on a determined driver workload; and/ora criticality level defined for said first information data set. If thedriver workload is determined to be high, the method can compriseinhibiting operation of the switching module; and/or returning the firstinformation data set to said first display.

The method can comprise transferring the first information data set fromsaid first display to said second display; or duplicating the firstinformation data set on said second display.

The method can comprise removing the first information data set fromsaid second display after the determined gaze direction has beendirected at the second display. The method could comprise checking thatthe driver has looked at the second display (whilst the firstinformation data set is displayed thereon) for at least a predeterminedtime period. The predetermined time period can be specified to ensurethat the driver has sufficient to comprehend the first information dataset. Alternatively, or in addition, the method can comprise removing thefirst information data set from said second display when the determinedgaze direction moves away from the second display. The first informationdata set could be removed at the same time as, or after the determinedgaze direction moves away from the second display.

The method can comprise selecting said second display from a pluralityof displays in dependence on a determined gaze direction of the driver.

DETAILED DESCRIPTION

A display control apparatus 1 for controlling the display of informationin accordance with an embodiment of the present invention will now bedescribed. The display control apparatus 1 in the present embodiment isadapted to control the display of one or more information data set INFwithin an occupant compartment (cabin) 2 of a vehicle 3.

The vehicle 3 is an automobile in the present embodiment, but theinvention is applicable to other vehicle types. The information data setINF can be one or more of the following non-exhaustive list of datatypes: a prevailing speed limit; a vehicle system notification/warning;an infotainment display screen; a satellite navigation instruction; acellular telephone notification (such as incoming/outgoing callinformation); and a climate control display.

A perspective interior view of a front portion of the occupantcompartment 2 is shown in FIG. 1. The occupant compartment 2accommodates the vehicle occupants, typically a driver and one or morepassengers, and includes various user interfaces for operating vehiclesystems. A first display 4 and a second display 5 are provided in theoccupant compartment 2 to display information to the driver of thevehicle 3 (and optionally also to the passenger). The first display 4 isa High Level Display Front (HLDF) disposed in a centre console 6disposed between a driver seat 7 and a passenger seat 8. The seconddisplay 5 is disposed in an instrument cluster 9 mounted behind asteering wheel 10. It will be appreciated that the second display 5 ismore closely aligned with a line of sight of a driver of the vehicle 3when they are looking ahead (eyes forward), as would be expected whenthe vehicle 3 is being driven with due care and attention. The first andsecond displays 4, 5 are in the form of display screens, for exampleliquid crystal displays (LCD), in the present embodiment. However, itwill be appreciated that one or both of the first and second displays 4,5 could be a virtual display, for example a head up display (HUD)configured to project a virtual image. In a variant, the first andsecond displays 4, 5 could refer to first and second display areaswithin a larger display. In this variant, the display control apparatus1 in accordance with the present invention can operate to vary thedisplay location of the information data set in said first and seconddisplay areas.

The display control apparatus 1 is configured to control the display ofinformation in the first and second displays 4, 5. In particular, thedisplay control apparatus 1 is configured dynamically to control theinformation displayed in the respective first and second displays 4, 5in dependence on driver tracking information. The display controlapparatus 1 is coupled to driver tracking means in the form of eyetracking apparatus 11 configured to track driver eye movements. The eyetracking apparatus 11 configured to output tracking data D1 identifyingwhere the driver is looking. As described herein, the display controlapparatus 1 receives the tracking data D1 and is operative to controlthe display of information on said first and second displays 4, 5 independence on where the driver is looking within the occupantcompartment 2. If, for example, the tracking data DAT1 indicates thatthe driver is repeatedly looking at the first display 4, the displaycontrol apparatus 1 operates to display a first information data setINF1 currently displayed on the first display 4 on the second display 5.By displaying the information data set INF1 on the second display 5, theinformation data set DAT1 can be viewed more readily by the driver,thereby reducing distraction levels. The first information data set INF1can replace or supplement a second information data set INF2 beingdisplay on the second display 5.

A schematic representation of the display control apparatus 1 is shownin FIG. 2. The display control apparatus 1 comprises a controller 12 oneor more electronic processors 13 (only one is shown for simplicity ofexplanation) and system memory 14 having computer code 15 storedthereon. The display control apparatus 1 is coupled to the eye trackingapparatus 11 to receive said tracking data DAT1; and to a switchingmodule 16 to control the display of said information data set INF1 onsaid first display 4 and/or said second display 5.

The switching module 16 is operable to display the information data setINF1 on either said first display 4 or said second display 5; or todisplay the information data set INF1 on both said first and seconddisplays 4, 5 (i.e. to duplicate the information). The display controlapparatus 1 generates a switch control signal SIG1 to control operationof the switching module 16, as described herein.

The eye tracking apparatus 11 comprises first and second image sensors17-1, 17-2 each comprising a driver-facing camera. At least one of saidfirst and second image sensors 17-1, 17-2 can comprise an infra-red (ornear infra-red) capability for eye-tracking purposes. In a variant, thefirst and second image sensors 17-1, 17-2 could detect light at avisible wavelength to determine head position and/or eye gaze. The firstand second image sensors 17-1, 17-2 are connected to an image processingunit 19 configured to process the image data to generate tracking dataDAT1.

The first image sensor 17-1 is located in a dashboard 21 below acentre-point of the front windshield W_(F), and the second image sensor17-2 is located near a bottom corner of the front windshield W_(F) onthe driver side of the vehicle 3. The first and second image sensors17-1, 17-2 are oriented inwardly into the occupant compartment 2. Thefirst and second image sensors 17-1, 17-2 have respective first andsecond field of view matrices. In operation, the first and second imagesensors 17-1, 17-2 each generate image data which is output to the imageprocessing unit 19. The first and second image sensors 17-1, 17-2 areconfigured to detect the driver and determine a point of origin inthree-dimensional coordinate space based on the position of the driver'shead. The orientation of the driver's head can also be determined moreaccurately to model the gaze direction and/or to determine anapproximate eye position for use by an eye-tracking mechanism. Theposition and orientation of the driver's head can be referred tocollectively as the “head pose”. The eye-tracking mechanism tracks thedriver's eyes so as to determine an angular direction of the driver'starget line of sight with respect to a fixed reference (known as “gazedirection”). In the present embodiment, the tracking data DAT1 compriseshead pose data and gaze direction data. The tracking data DAT1 is outputfrom the eye tracking apparatus 11 to the display control apparatus 1.The head pose data and the gaze direction data can be combined to form agaze vector representing a line of sight of the driver.

Since the first display 4 is disposed in the centre console 6, it wouldbe preferable to minimise the time that the driver is looking at thefirst display 4 whilst driving. The display control apparatus 1 analysesthe tracking data DAT1 to determine when the driver is looking at thefirst display 4. For example, a first area of interest A₁ is defined inthe system memory 14 to define the location of the first display 4; anda second area of interest A₂ is defined in the system memory 14 todefine the location of the second display 5. If the tracking data DAT1indicates that the determined gaze vector intersects the first area ofinterest A₁, the display control apparatus 1 determines that the driveris looking at the first display 4. Similarly, if the tracking data DAT1indicates that the determined gaze vector intersects the second area ofinterest A₂, the display control apparatus 1 determines that the driveris looking at the second display 5. It will be appreciated that thisanalysis could be performed by the eye tracking apparatus 11 and outputas a signal to the display control apparatus 1.

The display control apparatus 1 is configured to generate the switchcontrol signal SIG1 to control operation of the switching module 16 independence on the tracking data DAT1. In the above example, the switchcontrol signal SIG1 requests that the switching module 16 switchesdisplay of the information data set INF1 from said first display 4 tosaid second display 5 when the tracking data DAT1 identifies thedetermined gaze vector as intersecting the first area of interest A₁. Amodified switch control signal SIG1 is subsequently generated to requestthat the switching module 16 returns display of the information data setINF1 to said first display 4. The display control apparatus 1 can outputthe modified switch control signal SIG1 after a predetermined period oftime has elapsed, or in dependence on the tracking data DAT1. Forexample, if the display control apparatus 1 determines that the driverhas looked at the second display 5, the switching module 16 can becontrolled to return the information data set INF1 to the first display4. The display control apparatus 1 utilises the gaze detectiontechnology to manage the content displayed in the various screens. Thesystem can be used with or without a vehicle initiated dialogue system.

It will be appreciated that the occupant compartment 2 could be providedwith more than two displays. For example, the occupant compartment 2could comprise at least a third display 20. As shown in FIG. 3, thethird display 20 could be in the form of a head-up display (HUD) forprojecting a virtual image. Alternatively, or in addition, the thirddisplay 20 could be in the form of a display screen mounted to thedashboard 21. Alternatively, or in addition, the third display 20 couldbe a projection onto the dashboard 21 from a projector (not shown). Thedisplay control apparatus 1 could control the switching module 16 independence on the tracking data DAT1 determined by the eye trackingapparatus 11. For example, the switching module 16 could be controlledsuch that the information data set INF1 is displayed at least on thedisplay 4, 5, 20 coincident with, or most closely aligned with thedetermined gaze vector.

The display control apparatus 1 can be configured to control the dynamicdisplay of the information data set INF1 in dependence on a determinedcriticality of the information. For example, the information data setINF1 can be selected from a plurality of information data sets INF_(1-n)each having a predefined criticality setting (for example high, mediumand low criticality settings). The display control apparatus 1 can beconfigured to control switching of each information data set INF_(1-n)in dependence on the predefined criticality setting. For example, onlyan information data set INF_(1-n) having a high criticality setting (forexample a speed limit notification or a warning signal) may be displayedon a head-up display (HUD), whereas an information data set INF_(1-n)having a medium criticality setting (for example an infotainment displayscreen or a cellular telephone notification) may be displayed on thesecond display 5 in the instrument cluster 9. Furthermore, the displaycontrol apparatus 1 can control the period of time for which theinformation data set INF_(1-n) is displayed in dependence on thepredefined criticality setting. For example, an information data setINF_(1-n) having a high criticality setting could be displayed for arelatively long time period (for example 20 seconds), whereas aninformation data set INF_(1-n) having a medium criticality would bedisplayed for a relatively short time period (for example 10 seconds).Alternatively, or in addition, only some of the information data setsINF_(1-n) may be switchable between said displays 4, 5, 20. For example,the information data sets INF_(1-n) can each be defined as being fixed(i.e. non-switchable) or switchable. Those information data setsINF_(1-n) defined as being fixed are not switched between the displays4, 5, 20.

The display control apparatus 1 could optionally also be configured tocontrol additional output devices, such as audio devices and/or hapticdevices. For example, the display control apparatus 1 could selectivelyoutput an audio version of an information data set INF1 through avehicle audio system. This control strategy could be implemented if, forexample, the tracking data DAT1 determines that the user is repeatedlylooking at the first display 4.

The information data set INF1 could be switched to an alternate one ofsaid first, second and third displays 4, 5, 20 for a predetermined timeperiod, for example 5 seconds. Alternatively, or in addition, theinformation data set INF1 can be displayed on the second display 5 untilthe tracking data DAT1 generated by the eye tracking apparatus 11indicates that the driver has looked at the second display 5. Once thedisplay control apparatus 1 determines that the driver has looked at thesecond display 5, the information data set INF1 can be removed from thesecond display 5. The display control apparatus 1 could also be coupledto an input device 22, such as a button or switch provided on thesteering wheel 10, to allow the driver to acknowledge that they haveseen the information data set INF1. By way of example, the displaycontrol apparatus 1 can operate to switch the information data set INF1from the first display 4 to the second display 5 and, in dependence onactuation of the input device 22, switch the paste it back to the firstdisplay 4. The display control apparatus 1 can measure the time elapsedbefore the driver actuates the input device 22 and use this to determinean average time required for a particular driver to view the informationdata set INF1 once it has been switched to the second display 5.

The display control apparatus 1 could be configured to learn preferencesand/or behaviour patterns of a particular driver. For example, thedisplay control apparatus 1 could learn which one of a plurality ofdisplays 4, 5, 20 is looked at most frequently by the driver. Thedisplay control apparatus 1 can control the switching module 16 suchthat the information data set INF1 is displayed on at least theidentified display 4, 5, 20 looked at most frequently by the driver.

The display control apparatus 1 could optionally be configured todetermine a driver workload or to receive a driver workload signal. Thedriver workload can be determined with reference to a vehicle controlinputs, such as steering angle, and/or dynamic parameters, such asvehicle speed/acceleration. Data received from the vehicle sensors, suchas traffic monitoring sensors, can also be used to determine driverworkload. The display control apparatus 1 could be configured to inhibitswitching of the information data set INF1 between the first and seconddisplays 4, 5 when the driver workload is determined to be high.Alternatively, or in addition, the display control apparatus 1 canmodify the time period for which the information data set INF1 isdisplayed on the second display 5 when it is switched from the firstdisplay 4.

The display control apparatus 1 can optionally be configured to monitorhow the driver performs a particular task (or set of tasks), for exampleto learn how much time the user requires to perform a task and how oftenthe driver looks at the first display 4 whilst carrying out that tasks.The display control apparatus 1 may monitor driver behaviour indifferent situations, for example based on the current workload of thedriver or in particular driving conditions. The display controlapparatus 1 can be configured to modify how the switching module 16 iscontrolled in dependence on the historic driver behaviour.

The operation of the display control apparatus 1 while the driver isoperating an infotainment system will now be described. The driveroperates the infotainment system via a graphical interface displayed onthe first display 4, for example to select a particular radio station ora track from a playlist. The display control apparatus 1 determines thatthe driver workload is high since the eye tracking apparatus 11indicates that the driver is repeatedly looking at the first display 4.The display control apparatus 1 outputs the switching control signalSIG1 to control the switching module 16 to move or duplicate theinformation data set INF1 to the second display 5 or the third display20, thereby helping to reduce the driver distraction. The displaycontrol apparatus 1 can control the switching module 16 to return theinformation data set INF1 to the first display 4 if the eye trackingapparatus 11 determines that the driver is looking at the first display4.

The display control apparatus 1 can also operate to ensure that thedriver is made aware of critical information, such as a vehicle fault orwarning (such as a lane departure warning). In this scenario, theinformation data set INF1 can be in the form of a system alert. Thedefault setting is to display the system alert in the second display 5in the instrument cluster. However, the display control apparatus 1 cancontrol the switching module 16 such that the system alert is moved toanother display in the line of sight of the driver as determined by theeye tracking apparatus 11. For example, the system alert could be outputto the head-up display (HUD).

The content of the information data set INF1 can be modified dependingon the display in which it is to be displayed. For example, theinformation data set INF1 could be displayed in the first display 4 withan icon accompanied with a text description. When the information dataset INF1 is transferred to the second display 5 in the instrumentcluster, it can be in the form of an icon (“as present”). Moreover, whentransferred to the third display 20, the information data set INF1 canbe displayed as a text message (for example “Brake Fault”).

The display control apparatus 1 can be configured to determine thecriticality of the information data set INF1 and to assess the attentionrequired by the driver. The display control apparatus 1 can implement alearning strategy and implement one or more control functionsprogressively. For example, at least initially the display controlapparatus 1 may not transmit the information data set INF1 across all ofthe available displays 4, 5, 20 (e.g. general navigation commands).Rather, the system will initially only process the tasks requiringhigher attention tasks e.g. radio setting, warning, address entry etc.However, if the system detects that the driver is continuously givingattention to a navigation aid displayed in the first display 4 (forexample having to look at the second display 5 repeatedly, say 3 or 4glances, to check information), the display control apparatus 1 can beconfigured to recognise a problem and to prioritise that task. Theswitching module 16 can be controlled such that the display informationdata set INF1 is output to either the second or third display 4, 20which is more convenient for the driver and, thereby helps to reducedriver distraction.

It will be appreciated that various changes and modifications can bemade to the invention described herein without departing from the scopeof the present application. The display control apparatus has beendescribed with particular reference to a display screen or a head updisplay (HUD). However, it will be appreciated that the invention is notlimited in this respect. For example, the display control apparatuscould operate to control output of the information data set to anon-board projection system; and/or a connected consumer electronicdevice (such as a cellular telephone, personal computer or tabletcomputer) to display the information anywhere in vehicle.
